* Added astropy compatibility hooks for many LSL classes
* Moved from multiprocessing to concurrent.futures for multi-processing support
* Switched to multi-phase initialization for C++ extensions
* Merged ARX response files into single file per board to reduce number of data files
* Moved lsl.common.mcs value lookup functions over to enum.Enum classes
* Updated the lsl.writer.fitsidi to write antenna coordinates in the ECEF frame
* Changed 'elevation' to 'azimuth' in cases where it reference the angle above the horizon
* Updated the ImgWPlus class to have a 'wcs' attribute to help with mapping image to world coordinates
* Moved lsl.imaging.utils and lsl.imaging.overlays to using ImgWPlus instances for image to world coordinate mapping
* Added the Fermi 3FGL, 4FGL, and 4FGL-DR4 catalogs
* Updated many functions to be flexible with angle inputs so that accept float, astropy Angle or ephem Angle instances
* Fixed how lsl.reader.vdif and lsl.writer.vdif deal with non-zero reference epochs
* Added support for LWA-NA and other NDP-based stations
* Changed lsl.common.metabundle into a general module that can work with metadata from any station
* Added a DRX8 reader for future data format support
* Updated gatherDebugging.py to make it more useful
* Dropped the 'indicies' keyword from lsl.correlator.uvutils
* Added support for the (experimental) GloTEC ionosphere model

* Add a keyword to lsl.imaging.selfcal functions that will return whether or not a call converged
* Made lsl.readers.buffer.TBFFrameBuffer more robust
* Fixed reference counting in lsl.imaging._gridder
* Moved data used for unit tests from lsl/data to tests/data to keep them out of the install
* Various cleanups to internal regular expressions
* Changed the file downloaders to only show progress for interactive sessions
* Updated possm.py to works with the current version of LSL
* Removed aipy code in lsl.sim.vis in favor of direct calls to aipy
* Added support to the lsl.readers for returning DRX, TBN, and TBF data as "ci8" data
* Added support to the lsl.readers for returning VDIF data as "i8" data

* Added polarization basis conversions functions to lsl.imaging.utils
* Improved TBF frame count reliability
* Fixed several bugs in lsl.sim.dp.point_source() that lead to data that would not image properly
* Dropped unlzw in favor of using the gzip utility

* Added support for "long (ionospheric) product names"
* Updated the Hamming window coefficients
* Switched the PFB in lsl.correlator.fx to a Hamming window

* Updated the documentation in lsl.correlator.fx to clarify that 'pfb' overrides the 'window' keyword
* Added better documentation on the LWA data formats
* Fixed a bug in lsl.reader.ldp.TBFFile that caused it to die on files with gaps in the frequency coverage
